LASTING MACHINE.

Application tiled August 16, 1916, Serial No. 115,230. Renewed May 24, 1922. Serial No. 563,369.

for use in the manufacture of boots and shoes, and is herein illust-rated in its application to a machine for lasting the heel ends, or the heel seats, of shoes, the drawings showing a machine of the same general type. as that illustrated in United States Letters Patent No. 1,129,881 granted upon my application on March 2, 1915, in which type of machine it is one of the objects of the 1nvention to effect improvements. It will be recognized, however, that in many of its aspects and features the invention, is not limited to machines of the* type shown in said patent nor to machines for lasting the heel ends of shoes.

Among its important objects, the iiivention has generally in View the provision of certain improvements in lasting machines designed to insure better lasting on shoes in whih the uppers are made of comparatively heavy materials. One Way in which it is sought thus to improve the quality of the lasting on heavy shoes, as well as on shoes of the lighter grades, is by the application of heavy conforming and holding pressure to the upper about the end face of the shoe. For theaccomplishment of-this object the invention provides a novel organization .of-

means for effecting relative movement. between the shoel and a shoe end embracing band to seat the shoe in the band. The construction herein shown comprises means for imparting yieldingly to the shoe support a rearward movement of indeterminate extent yto force the shoe into the heel band while the band is maintained in substantially open position, thus insuring that the band` will apply substantial pressure against the end face of the shoe before sufficient pressure is applied by the band at the sides of the shoe to oppose substantial resistance to rearward movement of the shoe into the band. To

assist in accomplishing the object in view, the invention also' provides means for effecting a relative movement of the shoe and the band which is positive or of predetermined extent to increase the vpressure of the band against, the end face of the shoe and for locking the shoe in the band. n the construction herein illustrated a yielding rearward movement andI a positive rearward movement are imparted to the shoe support in succession prior to the operation of the wipers on the shoe, the last named move-.

ment taking place simultaneously with the closing of the band; and thereafter a further positive rearward movement is iinparted to the shoe support simultaneously with increased closing pressure of the band against the sides ofthe shoe between successive operations of the wipers, thus taking up any slack which may be occasioned by the tightening of the upper over the last in the first closing movement of the wipers and insuring a heavy pressure about the end of the shoe adjacent to the heel seat in the final overwiping operation. It is found that such application of pressure about the end ofthe shoe results in conforming the upper much more smoothly and tightly to the last and the insole than in the use of prior end lasting machines.

The invention also `provides, as an important feature, novel means for controlling the shoe in respect to movement in direc' tions transverse to the plane of the shoe bottom. In its embodiment of this feature, the construction shown comprises means for supporting the shoe yieldingly for a portion of the lastin operation, including in the construction s own the first operative movement of the wipers, and for holding it substantially rigid against pressure upon its bottom face for the remainder of the lasting operation. More particularly, the illustrative machine comprises means for upraising the shoe simultaneously with a positive rearward `movement of the shoe into the heel band and with the application of increased pressure to the band at the sides of the shoe after the first overwiping operation, and for then supporting the shoe rigidly against downward pressure as the wipers are suhsequently advanced and closed to completo the overwiping operation and thecoini'ircssion of the margin of the upper flat upon As a further provision for improving the quality of the lasting, theinvention provides' a novel organization.v whereby the Aupper about the end ofthe shoe is subjected to a kti htening or upwiping operation heightg This is effected in the wise Aof the shoe. construction shown 'by automatic depression of the shoe relatively to the heel embracing band prior to the overwiping operation of the wipers, thereby drawing the upper tightly about the end of the last toward the e wiped inwardly over the heel seat.y Such depression of the shoe, in the construction shown, is effected by a holddown which engages the heel seat face of the shoe and which serves thereafter, in co-operation with the shoe support, to control the shoe during the remainder of the cycle ofthe machine in the course of which the shoe is uplifted, as hereinbefore explained, between repeated operations of the wipers. It is also adesirable characteristicof the illustrated machine that in such uplifting of the shoe the band moves with the shoe by reason of the manner in which it is supported, thereby avoiding any tendency for the band to Wipe the upper reversely from the edge of the heel seat which might counteract in some degree the beneficial results of the upwiping operation. 'lo position the shoe initially for the lasting ope-ration, the machine herein shown has manually operated means for jacking the shoe upwardly against the holddown prior to the starting of the machine, and the rovision of such means for presenting the s oe, in combination with power means'for subsequently controlling the shoe, -constitutes another feature of the invention.

As a further feature, the invention provides a novel construction of end embracing wiper mechanism including, among other improvements, a novel and convenient means for effecting .relative adjustment of the wipers to conform them substantially to the shape of different shoes, for example to the different contours of the heel ends of right and left shoes. Such provision for adjustment is combined, in the construction shown, with means for imparting to the wipers positively an advancingfand closin movement of redetermined extent, there y insuring uni ormly effective results on heavy shoes which offer comparatively great resistance to the overwiping operation.

Still other important features ofthe invention are to be recognized in a novel combination and arrangement of wiper and tacker mechanisms, the term tacker being used herein for convenience ofk designation, although it will be understood that the invention is not limited specicall to means for driving fastenings in thev orm` ge of the heel seat before its margin isof tacks. "lhe machine illustrated includes 1n its organization what may be conveniently termed side tackers, arranged to drive end and corner tackers,where Athe gathersin the margin of the upper oppose comparatively heavy resistance to the advance of the wipers and tackers, are permitted to yield in response to such resistance while the Wipers continue their inward movement, this being particularly advantageous in the first o rative movement of the wipers for gatheringthe margin of the upper and laying it over the heel seat. The connection of the side tackers to the wipers results in their adjustment with the wipers when the wipers are adjusted as hereinbefore explained. The invention also provides for adjustment of the different tackers relatively to the wipers, as may sometimes be desirable for varying the tacking positions, the adjustments for the end and corner tackers determining 'the limits to which these tackers aremoved by f their yielding operating means. It is a further desirable characteristic of such limiting means that these tackers are prevented from moving too far inwardly during the first two 'advancing and closing movements of the wipers, thus avoiding interference with the holddown which otherwise might be engaged by these tackers.

The above and other features of the invention, including novel shoe end clamping means, novel means for turning and holding back the heel end of the sole of a turn shoe, and various details of construction and combinations of parts, will now be more particularly set.' forth Yby reference tothe accompanying ,drawings and pointed out in the claims.

As to general structure, ower transmission and automatic contro the machine shown herein corresponds to the 'machine shown in my Patent No. 1,129,881, previously referred t0.

The machine is provided with a base 2 from which rises a column 4 terminating in a head 6 carrying the heel seat lasting mechanism. This head is crowned by a frame 8 which carries a tack hopper and delivering mechanism. 4

A driving shaft 10 is journaled in the base 2 of the machine frame and carries a fast pulley 12 which is driven by a belt from a suitable source of power such as the usual line shaft, and is provided with a friction clutch disk 14. A second pulley 18 is loosely mounted on the shaft and is provided with a co-operating clutch disk 16. This second or loose pulley is connected by a belt with a pulley fastened to a sleeve 22 freely rotatable upon a driven shaft 24 and carrying a gear 26 at its inner end within the pulley 20. This gear drives the shaft 24 through suitable intermeshing reducing gears as shown in Fig. 2.

Adjacent to its rear end, shaft 24 carries a cam disk 28 having a cam groove 30 formed in its front face into which extends a roll carried by a reciprocating frame 31 having a yoke formation to straddle the shaft 24.

The movement ofthe shaft 24 is controlled by mechanism which may be substantially like that shown and claimed in my prior United States Letters Patent No. 791,986 of June 6, 1905. This mechanism need not be here more fully1 described than to state that a clutch operating rod 42 carries near its upper end a brake block (3o-operating with the inner face of pulley 20, with a spring 44 operating against its upper end and normally tending to move it upwardly to release the brake 40 and throw in the friction clutch 16 on shaft 10. The cam wheel 28 has a peripheral cam face 34 operating against a roll on a sliding block 32 to cause a trigger plate 36 to engage a slid- 1n spring latch 38 on the brake block to hod the brake against theY pulley and' against upward movement through the action of spring 44 until the latch is moved away from plate 36 by a finger 46 carried by a wedge block 48, this block being moved to operate the linger and release the latch and brake through a rod operated by a treadle 52. Toward the end of a revolution the plate 36 is permitted to rise by the cam 84, the latch 38 moving over beneath the 'plate and being subsequently depressed by the operation of cam 34 against the plate to move the brake block 46 and rod 42 downwardly to disconnect the clutch and stop the driven shaft 24 at the end of the revolution.

The machine includes suitable tack feeding mechanism which may be and is shown herein as corresponding to the tack feeding mechanism of Patent No. 1,129,882 of March 2, 1915, except that, as shown, fourteen tacks are employed and the number of tack pockets in the receiving plates and the number of raceways and slots, are varied accordingly.

Briefly, the tacks are fed from a hopper 54 which is oscillated by a rack bar 56 through a yielding spring connection 58 with the upper end of the'sliding frame 31 reciprocated through the cam 30. The tacks gravitate down a series of seven raceway grooves from the hopper to a separating slide which is arranged to be reciprocated twice in each cycle of the machine to deliver fourteen tacks to a receiving plate having fourteen tack pockets therein from which the tacks are discharged into conductor tubes leading to tack holding and driving units. An indicator such as is usually employed with machines of this character, is located at 59 (Fig. 1) and may be of any usual form. As shown (Fig. 2) the indicator mechanism is actuated by a plunger 61 connected to an eccentric portion of the hopper shaft 63.

The conductor tubes, as previously stated, lead to certain tack holding and driving units. These units are mounted within the head 6 of the machine frame and co-operate with wiping mechanism which is arranged to wipe down the marginal portions of the shoe upper over the edges of the insole at the heel end of the shoe, the tacks being subsequently driven. The last with the upper and insole mounted thereon is carried by a swinging vertically movable jack and is held in position relatively to the wiping and tack driving mechanism with its heel end within certain heel clamping means. which, together with the tackholding and driving units. wiping mechanism, and jack. is controlled from the driven shaft 24.

This heel clamping means includes a substud 64 secured to the forward end of a racked slide 66 (see Fig. 6).

The upper end of the stud supports a curved flexible steel band 68 having concave contact blocks 70 on its inner face arranged yieldingly to engage the back of the band 60 at oipposite sides of its longitudinal median line exibly of the last and shoe upper. A positive back stop between the upper and lower edges of the band and substantially in the longitudinal median line thereof is provided in the form of a block 72 carried'by the stud 64 and having a concaved band engaging face substantia y in the vertical plane 0f the corresponding contact blocks 70.

The forward ends of the clamping band are slidably supported by flanged clips 74 clamped to vertical studs 76 at the forward ends of links 78 pivoted at their rear ends to the head 6 (Fig. 4) at 80. Blocks 82, swiveled on studs 76, carry complemental pivoted plates 84 contacting with the opposite side faces of the clamping band adjacent to its upper edge. Pressure acting against the links 78, will, through these plates 84, cause the band to be clamped about the counter portion of a shoe upper positioned within the band. Movement of the band relatively to the pressure plates 84 will vary the pressure point on the band so that vby adjustment, the clamping pressure may be applied substantially at the same relative point on all lasts and shoes. The horizontal pivot mounting for the contact plates 84 causes said plates automatically to conform to the contours of the side faces of the lasts.

Adjustment of the band is secured by manually effected movement of the racked slide 66. This slide is suitably guided in the head 6 for movement toward and from the front of the machine. A spindle 86 is journaled in and extends transversely of the head and has a toothed end 88 co-operating with the racked slide, its opposite end projecting beyond the head 6 and carryino an arm 90 provided with a spring press n pawl 92 cri-operating with a stationary arcuate ratchet 94. Obviously` on pulling the pawl from engagement with the ratchet, the arm 90 and spindle 86 may be swung to move the racked slide and eti'ect desired adjustlment of the clamping band in the manner previously described. -The clamping band 60 in its rearmost position is adapted to accommodate a heel end of maximum size. Adjustment of the band forwardly positions it for Smaller Sizes, the adjustment for which may be indicated on the ratchet 94. In such adjustments the contour of the band is deterto which'it is slidingly movable.

The driven shaft 24, at a point within the head 6, `carries a. cam wheel 116 having its rear face formed as a cam 118 constructed and arranged to control the clamping and releasing4 movements of the heel band 60, and automatically to effect'and control movements of the last-carrying jack in the manner later to be described. A bell crank lever 120 (Fig. 9) is pivoted at one side of the, to conform the rear of the band to the end head 6 and carries at one end a roll 121 arranged to engage the cam 118, its other end being formed as a segmental rack 122 engaging and arranged to rotate a gear 124 carried at the outer end of a spindle 126 whose inner end is formed as a pinion 128 and engages with a rackon the upper face of a racked plate 13() positioned and guided in the head 6 for reciprocation in a horizontal plane slightly below the plane of the racked slide 66 as shown in Fig. 2.

The racked plate 180 is normally pressed outwardly and the bell crank roll 121 is held aganst cam 118 by means ofvcoiled springs 1232 acting against the plate. An equalizer 134 is pivotally mounted on the front end of a stem carried by and extending through the racked plate 130 and yieldingly held against forward movement relatively to the plate by a. spring. The equalizer engages notches in the sides of opposed rack bars 186 guided within the head 6 for horizontal sliding movement in the plane of plate 130 and positioned forwardly of the plate.

At opposite sides of the heel band, bell crank levers 138 (Fig. 4) are pivoted to thc head 6 and have their rear ends formed as racked segments to co-operate with racks formed on the outer faces of the oppositely disposed bars 136 which are reciprocated through the equalizer when the racked plate 130 is reciprocated through bell crank 120 and cam 118. The forward ends of the bell crank levers 188 are formed with transverse sockets within which are seated the outer ends of the tubular housings 140. Link rods 96 have their inner ends pivotally attached to the forward ends of the links 78 and have their outer ends extended through the outer ends of the tubular housings 140 and loosely fitted in and inserted throu h the perforated ends of the sockets in tie bell crank levers 138. The outer extremities of the link rods carry. nuts 98 or'other suitable means to retain them in connection with their bell crank levers. Coiled springs are seated within the housings 14() between the outer ends of the housings and the forward ends of the links 78 and provide a yielding connection between the bell crank levers 138 and the heel band clamping links 78.

lVhen bell crank 120 turns the pinion spindle 126 in one direction, the rackedplate 130 will be moved rearwardly and through the equalizer 134 will move the bars 136 rearwardly, in turn moving the forward ends of the levers 138 toward the heel band 60 and through the yielding connection with the links 78 forcing the heel band ends inwardly and forwardly into contact with the counter portion of the shoe. .Spring pressed pawls or detents 142 are pivoted at thelr inner ends on the links 78 and normally tend to engage their outer ends with fixed ratchet plates 144 adjustably secured to the frame of the machine, but are prevented lfrom doing so by pins 146 carried by and extending downwardly from the housings 140. When the bell crank levers 138 are moved inwardly toward the clamping band, the tubular housings 140 engaged by these levers are similarly moved, and the pins 146 Awill be moved relatively -to the springpressed detents to permit their springs to rnove them into engagementwith the ratchet plates 144 so that when the shoe counter is firmly clamped, the detents 142 will have been moved into engagement with the stationary ratchet surfaces and will hold the heel band lirmly clamped to t-he shoe until the levers 138 are reversely moved to release the heel band, whereupon the pins 146 will engage the sides of the detents 142 to force them from engagement with the ratchet surfaces.

The jack for supporting the last with the upper and insole attached thereto comprises a standard' 148 (Figs. 1 and 9) suitably guided lin a casing 150 journaled on the shaft 152 which is, itself, journaled in the column 4 of the machine frame. The standard has its lower end provided with a rack 154 and has a heel pin and last support at its upper end. Adjacent to its upper end the standard supports a forwardly projecting' toe rest bar 156 having thereon a horizorf tally adjustable toe rest support 158 on which a toe rest 159 is mounted for vertical adjustment. To the casing 15() adja cent to the upper end of the standard is pivoted the frontend of a rearwardly eX- tending rack bar 160 operated by certain mechanism to swing the casing and standard rearwardly to force and hold the heel of the shoe against the heel clamping band. 'lhe rack 154 at the lower end of the standard is arranged to be operated by power to lift the standard upwardly as a hold-down member is elevated as later described. y

shaft 162 (Figs. 2 and 9) extending transversely of the machine is toothed to co-operate with this rack bar 160 and has one end extended beyond the frame of the machine and provided with a ratchet wheel 164 (Figs. 1 and 9). An arm 166 carry-V ing a driving dog or pawl spring-pressed into engagement with the ratchet, is journaled upon this outer end of the shaft and is connected by a link 168 to the forward end of a rod 176 with which the lower end of a lever 170 has a yielding connection. The 'u per end of the lever' carries a roll 171 ig. 9) bearing against the outer cam surface 172 (Fi s. 9 and 10) of two concentric cam sur aces formed on the front face of the cam wheel 116. A coiled spring 178 encircling the rod 176 bears against the lower end of the lever 170, forming a yielding connection between the lever 170 and the arm 166 carrying the driving dog. Preferably, means are provided for ad'usting the tension of the spring 178, suc as the ratchet wedge block and the co-operating ratchet abutment handle shown 1n the drawings.

The plate 130 whose upper face is formed with a rack engaged by the pinion 128 has its under face slmilarly formed and engaged by a segmental rack on the upper end of a bell crank lever 180 (Figs. 2 and 9) pivoted on the machine frame. A link 182 is pvoted to one side of this bell crank lever and extends downwardly to and is lpivotally connected with a rock arm 184 car ried by a -sleeve journaled in the side of the frame column-4 and turning freely' on the spindle.162. This rock arm carries a spring-pressed'driving dog or pawl 186 arranged to engage a ratchet wheel 188 on the 1 spindle 162 to swing the standard backwardly.

A vertically upward movement of the standard is coincidently effected by a sectional rod 190 extending from the opposite side of the lower end of the bell crank lever 180 to a bifureated rock arm 192 journaled on the shaft 152 on which the standard casing 150 is journaled to swing and having a. spring 191 interposed between its parts to provide a pulling connection. The 'shaft 152 carries a pinion 194 meshing with-the standard rack 154 and also carries a ratchet wheel 196 engaged by a driving dog 198 mounted on the rock arm 192 so that upward swinging` movement of the lower end of bell crank lever 180 operates to move the .standard and last not only backwardly against t'ne heel band but also upwardly against the hold-down and to hold them in this position, the backward pressure of the extremity of the shoe against the band being unyielding since the jack is positively locked oru held back through the operating gearing.

This backward and upward movement of the standard and last is initiated subsequently to the preliminary backward movement of the standard and last effected through the cam 172. lever 170 and its driving conlill nections to the shaft 162. and terminates i subsequently to the termination `of said yieldingly effected backward movement as will be evident from the plot of the cam paths shown in Fig. 10.

band 60. He then swings the casing 150 inwardly and at the same time depresses a treadle 202 to raise the standard 148 to position the last at the proper elevation to be engaged by the hold-down 200.

This treadle, adjacent to its inner pivoted end. carries the lower end of an adjustable link 204 whose upper end is pivoted to the rear end of a lifting foot 206 in turn pivoted to the base of the casing 150 and having its front end positioned to engage the base of the rack bar 154 of the jack standard. Depression of the treadle 202. therefore, acts to lit't the standard 148 to effect preliminary positioning of the lasty andupper.

T he hold-down 200. previously referred to, is guided for vertical movement in a head 208 (Fig. 2) forming an extension of the head of the machine frame. Adjacent to its upper end, one face of the hold-down is formed with rack teeth meshing with a pinion 21() on one end ot a spin dle 212 journaled in said head and having a second pinion 214 thereon adiacent to its opposite This second pinion is engaged by a rack bar 216 guided in the head 208 and carried at the forward end of an adjustable rod 218 whose rear end is pivoted to one side of an offset bracket. on a cam-actuated lever 220 journaled at its upper end on the machine frame and having its lower end provided with a roll 221 co-operating with the inner cam surface 174 on the front face of the cam wheel 116. A second and substantially parallel rod 222 is pivoted to the other side of said offset. bracket on the cam-actuated lever 220 and extends through the head 208 (Fig. 9i. its end carrying a stop nut adjustablv to limit the degree which a coiled spring within the head and acting against the forward end of the rack har 216 (Figs. 2 and 9). may'swing the lever rearwardly to hold the lever roll against the cam 174.v ByV adjustingv this stop nut, the position of tliejroll 2 21 rela'- tively to cam 174 may be Ivariedfand yconsequently the degree to'which thehold-` down is moved -during thelasting operation."

The upper mounted on the last. when clamped and held in proper position, is operated upon by wiper mechanism to wipe over the marginal edges of the upper standing above the insole. and subsequently a series of tacks are driven in the wlped over edges. Accordinglv. the machine bed at a point above the racked plate is forn'ied with guideways to receive a sliding block 224 (Figs. 2. 3 and 5) having projecting upwardly from adiacent to its rear end a roll 226 extending into and engaging the sides of a peripheral cam groove 228 in the cam wheel 116.

The upper face of this block is channeled at 230 (Fig. 5) to form a guideway for the base 232 ot an end tack holding and driving unit 234. Below and within the edges ot the recess 230, the face of the block 224 is provided with an elongated recess 236 housing a coiled spring 238. the front end of which engages a stud 240 depending from the hase 232, and normally tends to move the hase with its tack holding and driving mechanism forwardly or toward the shoe.

The base 232 is formed with an elongated slot 242 therein (Figs. 3 and 7) and a pin 244 depending from a bracket arm 246 (Figs. 2 and 3) rigidly secured to the ma chine frame, co-operates with this,l slot, to

limit the cam actuated forward movement of the unit 234 bodilyv with the block 224 aus determinately to position the tacks beyond the inner edges ot the wipers when the wipers are partially withdrawn rearwardly for the tack driving operation. r1`he coiled spring 238 permits the base 232 to ltltl yield backw'ardly relatively to the block 224 when the opstanding marginal portions of the upper offer substantial resistance to forward movement in the first or breaking down movement of the wipers.

The block 224 has its forward end re.- duced in width and thickness and bifurcated to provide spaced legs 248, (Figs. 5 and 7 through which a tack block 324, secured to the base 232 extends. From a point adjacent tothe bifurcated end of the block rearwardly, the sides of the block 224 are formed as racks 252, arranged to operate the wiper mechanism through inter# mediateY connecting devices.

The --wiper mechanism includes complemental curved plates 254 havingtheir rear ends formedwith. rearwardly extending arcuate enlargements 256' having arcuate grooves 'and tongues.: the plates being pivotedtogether at the inner edge of their rear ends and said kgrooves 'and tongues being formed onv arcs having the pivot point of the plates as a'center;y To the under side ofthefwlegs- 248 ofthe block 224 a plate 2.60 is secured, this plate extending forwardly' and Yhaving a tongue and groove cuate grooves, and tongues of the wiper plates. and to support and guide the rear ends of the wiper plates.

The inner edges of the curved `wiper plates conform substantially tothe general contour ofthe heel end of a shoe. The rear end of the wiper or wipers formed by these plates is moved forwardly and over the heel of the shoe through cam actuated movement of the block 224 to 'wipe down that portion of the upstanding margin of the upper. The outer free ends of the wiper plates are moved inwardly toward the sides of the counter and of the bottom of the shoe and last to wipe down the side and corner marginalk portions of the upper b v mechanism operated through the racked sides 252 of the block 224 and best seen in Fig. 3 of the drawings.

At each side of the wiper at the outer end of its plates, a sliding plate 264 is mounted in the frame of the machine for sliding movement toward and from the shoe and last. As best seen in Figs. 1 and 3, each plate 264 at its outer end projects bevond the machine frame and is formed with an enlargement in which a spindle 266 is journaled, the spindle extending through the plate and its inner end being provided with a pinion 268. Fixed to the outer end of the spindle is a hand lever 270 carrying a suitable spring-pressed pawl (Fig. l) co-operating with a segmental ratchet 265 extending from and rigid with the end of the plate 264. This lever, pawl and ratchet mechanism may be of any suitable construction and is intended to pro vide means for adjusting the plate 264 toward or from the sides of the shoe and last.

In one form which this adjustment and the wiper operating means may take, comple-mental bell crank levers 272 are provided at opposite sides of the forward end of the block 224, the inner end of each lever having an arcuate rack to engage a rack face 252 on the side of the block 224, and the outer end of each leverhaving an arcuate rack engaging a pinion 274 having a spindle journaled in the machine frame and co-operating with the racked edge of a slide 276 (Fig. 3) whose outer end is formed with a rack face 278 engaged by the pinion 268.

Adjustably mounted upon the top faces of the plates 264 at opposite sides of the machine are the base plates 280 of side tack holding and driving units 282. Links 284 (Fig. 8) are pivotally connected to the under faces of the sliding plates 264 and to the outer free ends of the wipers 254. When the block 224 is moved forwardly through the cam 228, the double-racked bell cranks 272 will rotate the inions 274 to move the slides 276 inwar lly toward the Aplates inwardly toward the shoe.

shoe and, since the pinions 268 are locked against movement by the hand levers and ratchets the sliding plates 264 will be locked to the slides 276 and will be moved 1nwardly with them,. causing, through the links 284, the free ends and corners of the .wiper plates 254 to move inwardly and over the upstanding edge of the upper, thereby wiping the upper down over thc sides and corners of the heel seat, while at the same time the forward movement ot the block 224 will move the rear ends of the wiper plates forwardly over the end of the upstanding upper and will break and wipe it down over the heel seat of the shoe. Obviously, upon reverse movement of the block 224, the reverse'action will take place. The adjustment of the base plates 280 on the sliding platesA 264 which are directly connected to the wipers, positions the tacks a predetermined distance inwardly of the inner edges of the wipers at the sides of the heel seat', the parts being held in adjusted relation by clamp screws extending through slots in the plates 280 (Fig. 3). c

The hand levers 270 with their co-operating ratchets 265 provide means for independenti): adjusting the outer ends of the wiper plates 254 when the machine is at rest and when the slides 276 are locked by their connected gearing against movement. lVhen the hand levers are moved, the teeth of the pinions 268 will successively fulcrum against the teeth of the racks 278 and will move the sliding plates 264 with the attached side tack holding and driving units inwardlyl toward the shoe and will, at the same time, through the links 284, move the wiper Such an adjustment is necessary for affective wiplng action on shoes of different sizes and lasts. The location of the adjusting handles 270 on the outside of the head 6 at the front of the machine frame (see Fig. l) enables this adjustment readily to be effected by the operator. The described adjustment is additionally advantageous in that it permits independent adjustment of the wiper ends to take care of the different contours and swing of different heel seats.

The tack holding and driving unit 284 constitutes the end unit: the tack holding and driving units 282 at the ends of the wiper plates form the side units: and what may be termed corner units 288 eo-operate with the wiper plates between the end unit and the side units. These corner units 288 (see Figs. 3 and l2) are provided with flanged bases 286. seating in suitable guide` ways formed in the machine frame and extending obliquely to the wiper plates. Each of these units has a longitudinal bore in the outer end of its base plate to receive a coiled spring 290 whose outer end extends into a i wipers. 1 Except for ithe.- described and', illustrated socket formed in a tensioning screw 292 seating in the side of the machine frame (Fig. 3). The springs 290 operate against the corner units to move them inwardly to engage the wiper plates and to move them inwardly with the wiper plates when they swing in during the wiping operations.

Each base 286 carries on its under face in the plane of the edges of thel wiper plates, an adjustable stop plate 204 having an inclined inner edge to engage the outer edge of its wiper plate and to limit the position of tacks held in said unit to a determinate maximum distance inwardly of the inner edges of the wiper plates. This adjustment is made in assembling the machine. The tack positions may be varied within this maximum by varying the extent to which the springs 290 may move the units 288 inwardly toward and with the Wiper plates. Accordingly, the base plates 286 have rods 296 extending therefrom in the direction of their length out and through smooth bores in the sides of the machine frame. The ends of these rods are threaded and receive stop nuts 298 which engage the frame. and adjustably limit the inward movement of the bases 286 and their tack holding and driving units. By adjusting the stop nuts 298 which, as seen in Figs. 1 and 3, are located on the outer sides of the frame, the tacks in said units may be positioned less'than the maximum distance inwardly of the wiper edges predetermined by the initial adjustment of the stop plates` 294. It will also be evident that the stop nuts prevent the corner tackers from moving too far inwardly, where they might engage the holddown, in the first two advancmg movementsvof the differences in-their'bases and supports and in the' number of' tacks `held by the units, thev body structure of each unit is the same. As

p to body structure, the end unit 234 may-be describedas typifying this construction.

Each unit has a column upstanding from itsbaseY plate Aprovided at its upper-end with an obliquelyinclined cylindrical neck 300,'

the-innerv faces 'of the columns being under-` cut to offset the lower ends of the necks, and the necks having laterally and inwardly projecting offsets at their lower ends bored vertically to form tack channels 301 as best seen in Fig. 7. The necks have bores eX- tending longitudinally therethroughto receive. plungers 302 terminating at their upper ends in spherical knobs 304 seating in movable sockets in a hammer head 306 (Figs. 1 and 2) which is guided for vertical movement by a rod 308 upstanding from the head 208 of the frame.

A series of cushioned blocks 310 are adjustably carried by the head 208 and are arranged in the same horizontal plane to enassays? relatively to the head when their units aremoved during the wiping operations or are independently adjusted.

A lever 312 has its forward end bifurcated and pivotally connected to the head 306 (Figs. 1 and 2) and its rear end supported by an upstanding link 314 whose lower end is mounted in the machine frame. Intermediate of its ends, the under face of the lever is recessed to receive th-e upper end of an arm 316 (Fig. 2) which is pivoted to the lever at this point and whose lower end bears upon the periphery of a cam 318 mounted on the forward end of shaft 24. The lower end of the arm 316 is held against the cam 318 by coiled springs 320 (Fig. 1) encircling links 322 depending from opposite sides of the arm and guiding through offsets on the machine frame against which the upperv ends of the springs abut, their lower ends acting against abutment'nutson the lower ends of thelinks. The cam 318 is figured progressivelyto Vlift the arm 316 and theV head 306, compressing Athe springs the cam at.l this point having 'a sudden drop permitting the compressed `springs 320'.t0

downwardly'todrive the' tacks.

, Ifthe `Shoe' .being ,lastedl is formed of un# usually heavy, stock necessitating 'ar double g wiping cycle properlytoz wipe -down the edges, or, if for any other 4reason it ixda-v -si-red to repeat` the "awipingfoperation before tacking, the downward tack-driving thrust snapthe' `head 306' with the plungersg 302,l

loo I ofthe-head 306 at the end of lthe yc'yclemay i be prevented and the operator may immedi- 'atelyrestart the machine for a second cycle of operations. The arm 316, substantially in line' with the lower face of lever 312, is

formed with complemental shoulders 317 (Fig. 2)v on its opposite side faces. A bifurcated block 311, positioned beneath the lever 312 is arranged to be manually moved 'during the cycle to embrace the bar 316 with its upper face below the shoulders 317 so that the bar 316, when permitted by the cam 318, will be held'against effective down.- ward tack driving movement under the impulse of theV compressed springs 320. The j block may be moved into such position by. a

hand wheel 313 (Fig. 2) located on the outside of the head 6 and having a l spindle journaledv in the head and connected by a link 315 with the rear end of the block 311. The upper end of the link, when the block is Ymoved forwardly'to lock the driving head 306, will be positioned to engage lugs on the Luana? revolving tack hopper 54 to prevent a second oscillation of the hopper to feed a second set of tacks to the tack holdino' and driving units, and to co-operate witrli the hopper and its operating mechanism in the anner described in my prior PatentNo. 1,129,882 of March 2, 1915. It need only be stated here that a wedge member carried by the hopper operates automaticallv to retract the block 311 at the proper time during the repeated wiping cycle to permit tack driving movement of the head.

Secured to and depending from the lower ends of the plungers 302 are gangs of driver rods 322 (see Figs. 7 and 12) arranged to engage the heads of tacks to drive them into the edge of the upper after it has been wiped over the heel seat. To the base of each of the tack holding and driving units (in the case of the side and corner units, that portion of the unit projecting beyond the inner edge of the base'olate) is secured a tack block 324 (Figs. 3. 7 and 12) havino: its forward end projecting beyond the adjacent inner edge of a wiper late and having its upper portion provide with a number of tack receiving bores of a diameter to permit the tacks to fall therethrough and also to permit the driving rods 322 freely tobe plunged therethrough.

Rearwardly of these bores, the upper face of the tack block is formed with a stop shoulder 326. The under face ofthe tack block from its front edge rearwardly, is recessed to receive a sectional tack receiving and holding base comprising a grid having front and back walls 328` 330 and one or more connecting ribs 332, depending upon the number of tacks to be received. As shown in Fig. 3, the end unit 234 is designed to receive two tacks. and the corner and side units three tacks. Where two tacks are to be supported and driven. a single rib 332 (Fig. 8) will be employed and where three tacks are to be supported, two spaced parallel ribs will be used (see Fig. 3).

The inner faces of the front walls 328 will be cupped out to forni one half of an inverted substantially conical pocket, the apex of which is located at the bottom of the holder. These recesses will conform in number to the number of tacks to be supported and are located at opposite sides of the sin gle rib structure and between and at the outer sides of the ribs of the double rib structure as shown in the side unit 282 at the left hand side in Fig. 3.

The rear walls 330 will act-as abutments for the rear ends of coiled springs whose front ends are inserted in sockets in movable blocks 329 co-operating with the front wall and having shoulders formed on their upper faces to engage stop shoulders on the under faces of the blocks 324, (Figs. 7, 8 and 12). These movable blocks will have their front 'faces recessed to cor nd with the recesses in the front wall 328 to comp lete the conical tack receiving pocket. Obviously, when the drivers 322 are plunged downwardly, the front walls 328 will move forwardly and the blocks 329 backwardly to the thrust of the driving lrods 322 to mit the tacks to be forced from the pockets and into the wiped over edge of the shoe upper. The described parts are retained upon the tack block in assembled relation by means of a closureplate 334 (Figs. 7 and 12) having appropnately located side walls to enclose the movable blocks and their sprin and having -recessed front edges to permit the tacks to be driven therethrough.

These tacks are supplied to the' several units by the tack feeding and deliverin mechanism previously referred to throug a seriesof flexible wire tubes 336 extending from said tack feeding and delivering mechanism tothe various units. Accordingly, the oliset portions of these units are provided with two or three bores 301, as the case may be, extending vertically therethrough and counterbored at their upper ends to provide a diameter sufficient to receive the ends of the flexible tubes 336.

Below the bores 301 bored conductor plates 338 are mounted, their upper ends being pivoted to the offsets with their bores in the line of the corresponding tack bores in the offsets. The lower ends of these plates are normally positioned over andin alinement with the bores inthe forward ends of the tack blocks 324 and each against the stop shoulder 326 by means of a coiled spring interposed between the offset and the 'upper end of the swinging conductor ilatc. These conductor plates are, obviousy, each provided with two or more bores forming tack channels extending longitudinally of the plate and registering at their upper and lower ends with the bores 301 and the bores in the front ends of the tack blocks 324.

The conductor plates, at points in substantial alinement with the lower ends of the plungers 302 in their fully raised positions, are provided with lateral olisets 340 and the lower ends of -the plungers are beveled so that when they are thrust downwardly, their lower beveled lends will en gage the `offsets 340 and will swing the lower ends of the conductor plates away from the tack bores in the tack blocks, permitting the driver rods 322 to be thrust downwardly through the tack blocks to engage the supported tacks and -drive them from the conical pockets in the sectional base into the wiped over edge of the upper positioned below it.

The hold-down 200, best seen in Fig. 11 has its base channeled out to provide spaced yrcs contact 'orlbeari-ng faces 342, lpreferably Ythree in number and'triangulated .to rovide a contact ensuring' la. firm uniform.'y arlng'.

baseY carrying' the work support and Yis in and that-it supports lasting instrumentalities, the operation of which transmlts strain to the lasting head and to the base through the work support, which strain tends to spring said head and base out of this determinate angular relation. Means are employed for rigidly connecting the base and overhanging head and strengthening them against relative divergence through strain. As shown in Fig. 1, a brace or tie rod rigidly connects the base and the overhanging head.

The entire normal cycle of operations takes place in continuous sequence during one revolution of the driven shaft 24, one treadling only being necessary to operate the machine through a complete cycle, the shaft 24 being stopped automatically at the end of a single revolution.

The stop nut on the rod 222 may also beadjusted,'if necessary,.to change the amountof` lowering and liftingv movement of the `liolddt'mn"and to Y vary its initial-position.- The last and upperare now positioned -to be operated upon` by the machine. Accordingly, -the treadle 52 is`- depressed, throwing in the clutch and starting the revolution of the cam shaft 24.

At the beginning of -the revolution of shaft 24 (as willbe seen most clearly from the cam plots in Fig. 10) the cam wheel 116 will first bring the rise in the cam surface 172 against the roll 171 of lever 170 to start the preliminary backward power movement of the standard` and last previously described to bring :the rear end face of the shoe substantially against thc band before the band begins to close. After the completion of this movement, the cam surface 172 holds the lever 170 and its operating parts in the same position until the end of the cycle When the low part of the cam surface causes the lever and its ratchetoperating arm 166 toreturn to initial possition undertlie influence of a suitable spring.

At a point vduring this movement of the rise in the cam surface 172 against roll 171.

the first rise in the cam surface 118 will "racked plate 130 through l the previously. described `connettions,l the' `heel band tol clamp and conform shown in the'plot of ,thejcainpaths'in Fig is in4 its fhighest position;` the. wipersand opened-position.

Since the hold-down -is being moved downwardly, in a manner to bedescrib'ed, to upwipe the upper, cam operated movement of rod 190 to lift the jack standard is lost motion taken upby compression of the spring 191.

As the cam surface 118 operates through roll 121 and its bell crank lever to clamp the end of the shoe about the last, a rise in cam surface 174 operates against roll 221 and lever 226 to move the hold-down 200 downwardly, forcing, in turn, theheel end of the shoe and last downward relatively to the heel gripping band 6() which presses against the moving shoe and acts to npwipe the shoe 4upper over thesides of the last closely to conform the upper to the sides of the last in a manner similar to the upwiping action of the toe wiper plates on bed lasting machines when theftoe head with the wipers moves upwardly relatively to the toe end of the shoe. This downward movement of the last and shoe is effected without injury to the jack lifting connections since the spring 191 is compressed and takes the strain off these parts. Very substantial upwiping pressure is secured since the jack and shoe are locked back against the baud under relatively heavy pressure.

This downward movement of the shoe and last is figured to end with the bottom of the heel end of the shoe position slightly below the plane of the bottom faces of the, heel wiper plates 254 so that the shoe is positioned for the rst or breaking down movement of theiwipers, which follows.

The first inward and forward movement or breaking down wipe of the wiper plates occurs at the end of the clamping and' upwiping operations referred to, when cam wheel 116 brings the first outward bend in the peripheral cam groove against the roll 226 of the sliding wiper actuating block 224, moving the block forwardly to move the wipers with their (zo-operating tack holding and driving units inwardly and forwardly as previously described, and reversing the movement to retract the wipers and tack holding and driving units as the continued rotation of the cam wheel 116 brings the adi acent reverse bend in the groove against roll 226, the engagement of the terminal of this reverse bend with roll`226 withdrawing the wipers to their initial position of inactivity. This first wiping movement breaks down the upstandingmarginal portions of the upper over the heel seat butl does not iron them out fiat. since the last is not as yet moved up sufficiently to bring the heel seat substantially in the plane of the lower faces of the wipers.

Accordingly, as the roll 226 reaches the terminal of the reverse bend in they cam groove 228 which withdraws .fully the wipers, the jack and last, through bell crank lever 120 and its described connections operated upon by a second rise on the cam 118,

'are further pulled backwardly and upward- Coincidently, with the engagement of the roll 121 by the second rise on cam surface 1-18 further to lift-the jack and last, the holddown controllingaroll 221 encounters'a dro in the cam surface 174 permitting the racl; bar 216 to lift the hold-down coincidently with and proportionately to the second lifting movement of the jack and last. In the event of slight variance between the amount of lifting movements of the hold-down and jack the spring 191 will prevent any straining or breaking of parts.- These described heel band clamping, jack swinging and lifting, and hold-down lifting movements occur in the order stated` as the roll 226 reaches the described position at the end of the first As the cam wheel 116 continues to rotate.

the roll 226 and sliding block 2% will be similarly reciprocated a second time-for a second wipe over the now broken down marginal edges of the upper but with the last and shoe now raised to bring the top face of the insole substantially in the plane of the bottom faces of the wipers so that the marginal portions will be ironed down flat over the edges of the insole with the upper tightly conformed to the side faces of the ast.

A third bendin the cam groove 228 operates against the roll 226 to effect a final though only partial inward and forward wiping movement of the plates, the plates resting in this position for a short period to permit the lasting tacks to be driven while the wiped over edges are held down by the plates with the previously compacted and iron inner portions of the edges exposed to receive the tacks. The tacks will always be driven at points located definite distances from the inner edges of the wipers since the pin 244 definitely positions the tacks of the end unit, and the corner and side tack holding and driving units position their tacks as lircdetcrmincdlhv the described lac'liustments y 4for the respective units.

Toward the end vof the revolution of cam wheel 116, just before the wipers are finally retracted and the tack driving rods raised to permit the next set of tacks to be fed, cam surface 118 brings its lowest point in Contact with roll 121 of bell crank lever 120, causing the heel band to release the shoe and last. and rendering the bell crank lever 180 effective to return the ratchet operating arms 184- and 192 to initial position so that th x heel band i.: loosening and the jack is lowering as the wipers start to move to fully retracted position, the lever 170 also returning with the other parts. As a result, the pressure against the wiper plates is relieved and the wipers are retracted without any drag outwardly on the lasted edges. As the pawls 186 and 198 and the .pawl which engages the ratchet wheel 164 are'returned to their initial positions, they are engaged by suitable throw-out members to disconnect them from their ratchet wheels, f

as will b e understood by reference to Fig. 7.
